PUMP.

SPECIFICATION forming part of Letters Patent No. 654,323, dated J 111 724, 1900.

Application filed March 15, 1900- $erial No. 8,712. (No model.)

To all whom it may concern: H

Be it knownthat I, GOMERW. PRICE, acitizen of the United States, residing at 9 Stevenson street, in the city of San Francisco, county of San Francisco, and Stateof California, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates to improvements in pumping plants.

In the drawings, Figure 1 is a vertical sectional view of a well provided with a pumping plant mounted and constructed in accordance with this invention. Fig. 2 is a plan view of the pump and driving-motor as seen from above, the delivery-pipe and attachments being removed. Fig. 3 is a detail view, in side elevation, of an alternative construction for guiding the delivery-pipe when using a flexible pipe.

The objects which the present invention has in view are to provide means whereby a pump of the character known as centrifugal maybe connected directly with the driving-motor and both be maintained at a constant height above the surface of the water in a well and to provide means for deliveringthe water to the pump and from the pump independently of the height of the water in the well.

This invention consists in mounting the pump 2 and the driving-motor 3 on a float 4, which is constructed to have sufflcient buoyancy to carry the said pump and motor and the suction-pipes 5 5,which are suspended from it. The float is constructed to fit the casing of the well and is guided in its rise and fall by the guide-rails 6 6, for which purpose it is provided with the grooved rollers 7 7 to run on the said rails. The pump is provided with the rigid pipe-section 8, to which is connected the lower end of the delivery-pipe 9, which may consist of a flexible extension, as shown in the drawings, or of a telescopic pipe. When using the flexible delivery=pipe,

some means,'such as the large pulley 10 or the series of small pulleys 12 12 (shown in Fig. 3) must be used to bend the pipe over and have it run freely. To maintain the "flexible pipe taut, I provide a take-up thereby. To insure a better and more constant flow, one or more borings are then sunk and pipe-casings 17 17 are placed in position reaching to just above the bottom of the body of the well.

In many localities the supply of water is uncertain and the body of the well may at one time have considerable water in it and at another time be practically empty. It has been to accommodate this variation that here tofore the pump has been placed at a low level in the well, caloulatedto be submerged at high water, and has been connected by a shaft direct with a motor placed above the surface of the ground. This manner of mounting the motor upon a pump of the character specified has rendered it necessary that the pump be mounted horizontally and that the delivery-pipe leading therefrom be bent near the outlet of the pump. This, together with the necessity for supporting the long vertical shaft and the motor, if mounted thereon, has diminished the efficiency of this character of pump.

The motor 3 employed in this invention is an electric motor, the wires 18 for which are provided with a take-up, as shown. This motor is directly connected with the driving shaft of the pump, and the shaft is mounted in horizontal bearings. The delivery-pipe leads directly upward from the pump. In this manner is the difficulty heretofore experienced avoided. With a pumping plant thus constructed and mounted the pump is maintained at the same level above the water at all times, be there much or little water in the well-body. It will follow the water downward, being evenly guided, until the float 4: rests on the top of the pipes 17 17. Even then it will continue to draw water from the casings 17 17. At the same time should the 1. In a pumping plant, the combination with a suitable float; of a pump mounted on the upper surface of said float; and having a driving-shaft; a motor mounted on the said float and connected to the said shaft; suction-pipes connected to the said pump and depending from and supported by the said float; casings extended below the bottom of the well-body to receive the said suctionpipes; and an extensible delivery-pipe leading from said pump to above the surface of the ground; substantially as described.

2. In a pumping plant, the combination with a suitable float; of a pump mounted on the upper surface of said float; a motor mounted on the said float to drive the said pump; suction-pipes connected to the said pump and depending from and supported by the said I float; casings extended below the bottom of the well-body to receive the said suction pipes; an extensible delivery-pipe leading upward from the said pump; vertical guide-rails mounted in the well-body to guide the said float in its rise and fall; and suitable rollers mounted on the said float to engage the said rails; substantially as described.

3. In a pumping plant, the combination with a suitable float; of a pump mounted on the upper surface of said float a motor mounted on the said float to drive the said pump; suction-pipes connected to the said pump and depending from and supported by the said float casings extended below the bottom of the well-body to receive the said suctionpipes; a flexible delivery-pipe leading upward from the said pump; 'a suitable take-up mechanism for maintaining the delivery pipe straight Within the well; vertical guide-rails mounted on the well-body to guide the said float in its rise and fall; and suitable rollers mounted on the said float to engage the said rails; substantially as described.

In testimony whereof I have hereunto set my hand this 30th day of January, 1900.
